What are the differences in design or features between the 27D and the Lite?  
--------------------  
in order to reduce the cost, a number of features are removed from the 27D as well as using lower grade components. the circuit however is the same. as far as components are concerned, the major difference will be the type of capacitors, resistors, relays, transformer as well as display. for example, for the 27D, it uses v-cap teflon for output and power supply by-pass while the 27D lite uses Aura Telfon and Gnostic own MKP cap. if you look at the retailed price, the vcap 2u cap is US$460 a piece while the Aura is US$180 a piece.  
as far as features are concerned, many monitoring features are removed, no control to set the sound preference, only 3 inputs, 1 output. etc  
 
27D lite still sound very similar to the 27D. but as you know, it is a law of diminishing return.  
--------------------------------------------------------------  
 
King,  
 
As an audiophile myself, I am waiting eagerly to hear the 27D Lite version, while I am sadly missing 27D's sound. :-)  
 
Please do some write-up to announce the Lite version in the website!

The 27D is ready for delivery this Wednesday. Looks like we may have a tube pre-amp gathering sometime by the end of this month, or alternatively a DAC contest, whichever is the more popular.

Thanks Anthony, I have visited their web-page too. To be honest, the best track from their CD is still a far cry from the LP counterpart I happen to have in my collection.

ABC 會唔會又好似 SHM-CD 咁呢?有無 D 曲目可以同普通銀/鋁 CD 比較下呢?  
 
希望 ABC 可以帶來驚喜,應該幾好玩。

Hi, Sinfu,  
 
This CD is issued by ABC International Records in China of which they have a contract with Mark to convert a lot of old recordings into the CD. I am a great fans of ABC as a lot of their record is really good at very reasonable price say HKD 50. This is the link for their website, They have also connected to Burwen Bobcat in converting some  
 
The shirley 's voice is also one of my favorite.

The making of our own tape-to-CD turned out to be much more sticky and complicated than we had initially anticipated. From this perspective, therefore, I heartily appreciate the amount of effort that must have gone into the production of this high quality CD, uncertainties over its legitimacy notwithstanding.

This is the best Master Tape to CD transfer I have come across so far. It was given to me by gingers whose CD player refused to spin the black pro-looking disc. The origin of this CD is rather suspicious since exalted names like Kenneth Wilkinson and Mark Levinson are all quoted. Can anybody help to shed some light on this?

Hi Vash,  
 
It's base on famous Williamson circuit to modify, it can provide around 15~20W in triode mode and 30~40W in ultra-linear mode. It drive my 4 ohm Mezzo Utopia quite good. Welcome to listen.  
 
50~80W power amp, you can consider KT88 OR EL156.

Dear dalik (a.k.a. gijoe2222 ),  
 
Would you mind tell me which circuit is it ? How much power on the output ? I am thinking of building a 50~80W tube power amp. for 4 ohm speaker load, any suggestion ?

Takman Carbon film resistor, more or less like RMG! Very detail, good sound and reasonable price.  
But only 0.5W & 1W!
